IlYlPBfO-ED SHUTTEB. FASTENING.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, .WILLIAM B. HOWARD, of Baltimore, in the county ofBaltimore, and State of Maryland, have invented a new andjinprovedShutter Fastening; and I do hereby declare the following to be a. full,clear, and exact description of the same, suicient to enable one skilledin the art Ato which the invention appertains to make use of it,reference being had to the accompanying drawings, which forms a part ofthis speciiication, and in which- Figure 1 is a front elevation of theshutters closed.

Figure 2 is an enlarged view of a single fastening in elevation.

Figure 3 is a side view of a single fastening in its lockedlposition.

Figure 4 is a. top view of' a. single fastening in the act of closing.

Figure 5 is a. Bide elevation of a. single fastening in the act of.closing.

A tumbler is pivoted to a. bracket, which is attached to the jamb or theshutter. By the opening of the shutter it is raised, and when theshutter is fully open it falls between two cheeks on the bracketattached to the other object.

In the drawings, A A are the jambe of the window casing, B B theshutters. In the case of the shutter B the fastening is attached midway.between the-hinges H H, and in the case of the shutter B the fasteniugsare placed in the vicinity of the hinges. The fastening consists of twoportions, which are attached, respectively; to the jamb 'or to theshutter. One portion has two cheeks, G F, on a bracket, E, and the otherportion has a. pivoted tumbler, D, on a bracket, C. The brackets areconstructed especially for right and left-hand shutters; but the tumblerbracket may be on the shutter o1' jamb, the other bra-akelneing:attached to the other object. l

The operation is as follows: The shutter being opened, the lower edge ofthe pivotetnznbler strikes Athe .inclined plane F on one of the cheeksof the bracket E, and is thereby raised; the shutter Acontinues to openuntil it strikes back against the walk-when the tumbler D falls downbetween the G F, end .is then locked, fastening the shutter open. Toclose the shutter, the tumbler is raised, which frees it from thefastening.

Having described my inventicn. what I claim as new, and desire to secureby Letters Patent, s The arrangement of the tumbler-bracket C D and thecheck-bracket F G E, constructed and operating substantially asdescribed and represented.

WM. B. HOWARD.
